,SIGNORS TO VACUUM OIL COMPANY, OF NEW YORK YORK, N.-Y., A CORPORATIONOF NEW INCLOSURE FOR ARTICLES BEING SPEAYED Application filed May 14,

The present invention relates to inclosures for articles being sprayedand an object of the invention is to provide an inclosure into whichCylindrical receptacles may be readily fed from a conveyor and fromwhich they may be readily discharged onto another conveyor. Anotherobject of the invention is to provide a casing having inlet and outletdoors on opposite sides thereof and provided with a rotary means whichpermits all portions of a container to move past a spray gun posi tionedat one point in the casing. Still another object of the invention is toprovide for covering the upper head of a container as it is beingrotated in an inclosed casing past a spray gun, in order to protect thehead against this spray. A still'further'object of this invention is toprovide a common operating means for the'doors of a casing and a coverfor a container rotating in the casing past a spray gun.

To these and other ends, the invention consists of certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings:

Fig. 2 is a plan view of the same appara' tus;

Fig. 3 is a rear view;

Fig. 4 is a view of the intake side of apparatus;

Fig. 5 is a vertical section through the apparatus; a

Fig. 7 is a detailview of the head cover operating mechanism. 4

In the illustrated embodiment of the invention there is provided a mainframe 1 supthe porting a casing or housing comprising, in

this instance, two segments 2 of a circular wall. spacedat their lowerends from the lower part of the frame and spaced at their vertical edgesfrom each other to provide an intake opening and an outlet opening 3 and4 respectively. The intake opening is closed 1927. Serial No. 191,506.

by a door 5 while the outlet opening is closed by a door 6, the door 5being narrower than the intake opening so that a vertically extendingopening 7 is provided between the free edge of the door and the adjacentedge of one of the wall sections 2 through which a spray gun may beoperated. The door 5 has a hinge bar 8 turning in bearings 9 while theIn this instance, the hinge bars 9 and 10 have arms 13 extendinglaterally from their upper end. .To one of these arms a link 14 ispivoted at 15, said link in turn being pivoted at 16 to 1 an operatinglever 17 which is pivoted at one end 18 to the frame 1 and has its otherend provided with a grip 19. 'To the other arm 13, a link 20 is pivotedat 21, this link 20 also being pivoted at 22 to a link 23 which ispivotally connected at 24 to the knuckle of a toggle formed by two links25 and 26, the former being pivoted at 27 to the frame 1 and thelatterbeing pivoted at 28 to the lever 17. It is apparent with thisarrangement, the movement of the operating lever 17 in one directioneffects the simultaneous opening of the intake and outlet doors, whereasthe movement of the lever 17 in the other direction effects thesimultaneous closing of thedoors.

Within the -lower portion of the casing is mounted to turn arotary tableor support 29 which may have a pulley 30 beneath the same operated inany suitable manner. In this instance, a belt 31 passesabout the pulley30, thence upwardly about two pulleys 32 to a loose pulley 33 on a driveshaft 40. This drive shaft carries a drive pulley 41 which through aclytch connection 42 is adapted to establish driving connection with thepulley 41 in order to effect the turning of the table or rotary support29.

In order to effect the automatic stopping and turning of the rotarytable 29, the movable member of the clutch connection 42 may beconnected to a lever 43 which. is pivoted at 44 to the frame of theapparatus and has a depending end. Pivoted at 45 to the lower end of thelever 43 is a rod 46, the otherend of which is pivoted at 47 to theoperating lever 17 so that when the operating lever is moved to closethe doors, the clutch connec-' tion 42 will be established and therotary support 29 will start a motion, whereas, when the operating lever17 is moved in the opposite direction, to open the doors, the clutchconnection will be broken and the rotary support will cease itsrotation.

With the end in view of protecting the upper head of the receptacleagainst the spray, a head protector or cover 48 is em-. This headprotector is inthe form ployed. of aconcavo-convex disk 48, rotatablysup ported on the lower end of a rod 49, which is guided for verticalmovement through the the link in turn being pivoted at 47 to the lever17. The apparatus is preferably used in connection with a feedingconveyor 57 and "a a discharge conveyor 58.

The operation of the invention will be understood from the foregoing butwill be summarized as follows: the containers 59 move along the feedingconveyor 57, while an operative stands at one side of the feedingconveyor in, position to grasp the handle I9 of the operating lever 17.Movement of this lever in one direction opens both doors 5 and 6 of theapparatus and also elevates the cover 48 and stops the rotation of thetable 49. The

operative with his hand pushes the container 59 onto the table orsupport 29 and this container displaces a container from the rotarysupport onto the discharge conveyor 58.

. When the newly entered container is properly centered on the rotarysupport 29, theoperative moves the lever 17 in the other direction, thusclosing both doors 5 and 6, starting the rotation of the rotary support29 and moving the cover 48 into engagement with the upper head of thecontainer. The concave surface of this cover tends to properly centerthe container on the rotary support as the center of this concavesurface is vertically above the axis of rotation of the rotary support.The operative with a spray gun of any suitable construction sprays thecontainer through the opening 7 and the fumes from this coating materialpass off through a discharge flue 60.

What we claim as. our invention and desire to secure by Letters Patentis 1. apparatus of the class described comprising a casing having adoor, a rotary container support mounted in the casing to engage one endof the container, a cover mounted in the casing for engaging theopposite end of the container and common controlling means for effectingthe closing of the door and the movement of the cover toward the rotarysupport. a 1
